Add-on condition: checking if user has logged in

Hey there.

First off, great board.

I've got a custom upload script that I'd like to use. I'd like to restrict access to it to registered users that are allowed access to my private forum.

What I'm curious is what do I have to include in that will allow me to check login state?

I've searched the forums, but haven't found anything of use.

Thanks very much!

You need to include it... hmm, depends on script itself :) Actually, somewere in the middle of index.php, there is a definition of User ID ($user_id variable), so you need to catch this var and get on it...

Well, it's just an image upload script. I'd like to allow my registered users who are allowed access to the private forums access.

What I'm having trouble finding is the function that checks to see if a user is in that array.

If $user_id!=0 - then this is logged & registered user.
